Reacting nitrous acid with aromatic amines to produce diazonium salt is one of the most used processes. An aromatic amine called aniline reacts with nitrous acid to generate benzene diazonium chloride, a diazonium salt.
To create azo colors, benzene diazonium chloride combines with phenol, -napthol, aniline, and 2-methylaniline. These reactions result in the removal of an HCl molecule. Red organic dye is created when benzene and benzene diazonium chloride interact. Since the solutions created in this method do not last, the reactions involving a diazonium salt are always carried out with a freshly prepared solution. Diazonium salts are very flammable when they are solid because of their instability.

Answer:Two Main Types of Pure Substances
Elements and compounds are the two types of pure substances. Examples of common elements include carbon, nitrogen and hydrogen. They consist of one type of atom and cannot break down into something else. Every pure carbon substance, for example, has the same particles in it.
Explanation:I think
Answer: Option (A) is the correct answer.
Explanation:
It is known that when sharing of electrons take place between two combining atoms then the bond formed is known as a covalent bond. In general, a covalent bond is formed between two non-metal atoms.
For example, the compound HCl has a covalent bond between the hydrogen and chlorine atom. As hydrogen atom has 1 valence electron and chlorine atom has 7 valence electrons.
So, in order to attain stability both these atoms will share their valence electrons and hence, a covalent bond is formed.
On the other hand, when an electron is transferred from one atom to another then it tends to form an ionic bond.
For example, the compound NaCl has an ionic bond.
Thus, we can conclude that when atomic orbitals of two nuclei overlap, the mutual attraction between a negatively charged electron pair and the two positively charged nuclei forms a covalent bond.
